soundverse Capability
Singing Generation
Generate a vocal performance from a prompt and lyrics, optionally guided by a reference voice sample. Available in v5, v6, and v7.
Compat route available
POST /v{5,6,7}/generate/singing covers generate_singing with old-style field names. This is a new URL, not a literal recreation — the old singing endpoint was version-less (/v2/generate/ai-singing-gen), predating the v5/v6/v7 family entirely, so this path is offered for consistency with the rest of the compat surface rather than resurrecting the old one. See Compat Routes.
Quickstart
POST/v7/generate/singingcompat route, simplest way to start

-H "Content-Type: application/json" \
-H "Idempotency-Key: singing-req-001" \
-d '{
"styleOfMusic": "warm soul, female alto",
"lyrics": "walking through the city lights...",
"audioUrl": "https://example.com/voice-sample.mp3"
}'The compat route maps styleOfMusic→prompt and audioUrl→vocal_reference internally. Response: 201 {"job_id": "...", "status": "queued"}.
